For top 20 it's 8000x$1.4=11200USD approx at current market rate of Steem. Can't say what it's like at the bottom of the list as im unsure of the hardware anyone else is running. I knew someone who used to run a node reliably at less than $20 a month lol. He's disabled the witness since then afaik.

that actually sounds pretty great, especially since it has been a whole lot higher than $1.4 in the past. is there like a tutorial or a guide for setting up one of these nodes for the STEEM blockchain for dummies?
